yeah autoworx = fail. got home then realised the wrx was in snow mode so made 160 on 8psi when it normally boosts to 15. cant believe those fools didnt catch it "ah we cant figure out why but we aren't getting a boost reading"

Shouldn't you have changed the mode when you got there?

Celica readout must be awesome i must sell c210 and get one

Yeah, it is pretty rad.

I think everyone was having issues on the dyno...

Next time lets not try organise an event for the hottest day of the week it's now happened twice in a row...no wonder my car isn't happy with me. Haha

Bretto is happy

[V8EATER]

Not anymore. I think the cometic head gasket on the GTR went pop. Lost total compression on number 3 and 6. No smoke, no rattles, no breathing of engine so i think head gasket couldn't hack the 16psi and said "fuck this, im out of here". Im sorta glad its done it now and not when ive done all the mods winding it up to 22. It could be worse. Im hearing air bubbles also in the head when the car is off. It's a head gasket for sure.

If it is the head gasket, ive now caught onto everyone saying there shit and that i will never use another Cometic head gasket again.

Well....

Bad day is bad?

[REAPER]

i had fun

[2LV8ETR]

Had my work do this day - Had to be a lunch deal as well. Always the way.

Brett - Let me know when you get the shit together to sort your car and I'll be there to help out.

Cheers bro. I did the gearbox in the silver skyline today so ive got some wheels to use until we both have time mate to pull the engine out. Now that dyno day and track day are done, it can sit there until crissy time to get done. While its out i want to put the heat wrap on the tomei exhaust manifolds as their just generating too much heat which is heating the oil and water lines above the manifolds. Theres no air flow to keep them cool.

No i can't put hole in bonnet

Just quickly, for anyone else who thought perhaps their car didn't make the power they were expecting...

I just realized that Autoworx backed off the throttle on my car at 5600rpm. My car revs to 7500rpm, making 390rwhp by 7000. After overlaying my graph from Autoworx with my graph from Allstar (tuned the day before), at 5600rpm on my Allstar graph I am making about 330rwhp. So looking at that, my result at Autoworx of 319 isn't that far off.

Anyone know why they stopped at 5600??

what kind of cometic head gasket? metal / multi layer? may be worth checking oil temp, if your planning for alot of hp you really need a good oil pump

[V8EATER]

What its got now is a 1.2 metal head gasket. Actually one that C Red supplied and said "It should be ok". Well we will find out when it comes apart once again.Oil pumps already done dude. Its got a nitto HV pump. I didn't skrimp on that one. Got a a tomie baffle kit too.

Martin i think the dyno was near to close as what it should of been. That Grey GTR, when i spoke to him i asked him before he put it on the dyno what HP it was making and he said that he was making around 410 - 420HP. Well the figures were 414HP. He said thats about right so im thinking it's right.

[Hanaldo]

Yeh well it is pretty much spot on, it's just that they stopped early with mine. My graph ends at 5600rpm. That's pretty much spot on with my Allstar graph at the same rpm, considering Allstar had SAE correction method turned on. Correction adds about 6% on top of the genuine figure; 318.7x1.06 = 337.8. If you compare the graphs:

Allstar:


Autoworx:



At 5600rpm on the Allstar graph, it's pretty much spot on 6% above the Autowrox reading. But it's an incomplete run, I still had another 2000rpm to go which is unfortunately where a large chunk of my powerband is with this new turbo. Not whinging about the number, it's just a number. Just wondering why they stopped the run so early.

[Socrates]

When we had the last dyno day, when i told the dude to not rev over 6k with my car, he said he normally goes until it starts to lose power.
That is the case with yours, at 5800 on that day the engine started losing power.

Why is your power delivery so lumpy on the allstar graph?

[Char]

yeah the autoworx dyno sheet actually looks alot better than your allstar one

[Hanaldo]

It's just the resolution of the graph. They are very similar curves, Allstar's just has a higher resolution.

And I believe the power curve dips down after 5600 because they backed off the throttle. The car wouldn't have started losing power in the middle of the rev range just after the turbo came on full boost. They probably saw the same flat spot that is on my Allstar graph and stopped the run, whereas it actually would have picked up again.

Why do you make max power at 7000rpm :|. Isn't that redline?

[Hanaldo]

Why do you make max power at 7000rpm :|. Isn't that redline?

Nah, redlines at 7500.

[Hank Scorpio]

Haha, mycar started losing power at about 2,700rpm - and it still whooped all your candy asses, lol!

[Socrates]

Must be something wrong with it lachlan, max power should be around 5 - 6k for those

[Ten Four]

Its old Socs lol and don't know what previous life its had... Leave it alone!!

Fk'n lol! You must give your cars shit Socs, redline is only at 5,500rpm and it may have lost a bit of curry in it's 29 years of existant.
